CS 178 - Digital Photography (Spring 2011)

What's inside a digital camera? This is a cutaway view of the Canon Digital
Rebel 1000D. Here's a more instructive
diagram, showing the main optical paths. We'll take apart a camera in
class.

Most photography books talk about depth of field and depth of focus, but few of
them give a formula for it. Here it is. N is the F-number, f is focal length,
C is pixel size, and U is distance to the scene. We'll study this formula in
class, and you'll be asked to experiment with depth of field effects in your
weekly photographic assignments.

This is a tough shot, because the arcade ceiling is much darker than the
courtyard beyond. I solved it by combining three exposures, an idea called
"high dynamic range" imaging. You don't need a special camera for this; we'll
try it in class. Here are more shots from India.

Dorothea Lange's iconic portrait of a migrant mother during the Great
Depression. We'll survey the history of photography and study
the work of good photographers.
